I do a lot of mountain bike trail mapping work using OpenStreetMap, and it's really bugged me that more public-service mapping projects (eg: MTB Project) don't build on OSM. They all tend to instead build their own mapping set which requires stuff to be re-entered... It's kind of a pain.

Similarly, a lot of charitable organizations that could be releasing data to build on top of the OSM dataset and the tooling that exists, instead create their own data silos. For instance, Sustrans (the cycling charity in the UK), and the Ramblers (the walking/hiking charity in the UK). I get the impression that managers are coming up with ideas for their digital projects without any reference to the technical landsc…

I've been trying to learn the world of GIS for a cycling/pedestrian project I've been working on over the last few months. I'm also working with the local Open Data/Open Government groups. As I've gotten to know the communities I've seen this over and over...even in the Open Data groups.

I've come to the conclusion that it's not malicious (or even 'Not Invented Here' syndrome), but ignorance and a complete misunderstanding of the FOSS world. It seems that a lot of the people and groups involved come from a corporate background where they had to build and keep everything in house. Whenever I mention not reinventing the wheel, building on others work, collaborating with other groups, or opening up our the data I'm met with mostly blank stares. (I could go on and on about this disconnect and why I think it's happening, but it's not directly relevant to your comment.)

I think the major issue is that non-developers (and even some developers) have no idea how to work with others. It isn't that they don't want to or are refusing to, they fundamentally just don't know how to. The idea of working with more than the fifteen people that are present in the room is mind-boggling, let alone the idea of working with people all around they world they may never meet. On top of that simple issue you have the same concerns you do with any person outside the Open* communities: security, trust, liability, etc. Have you ever seen a layperson look at a software/data license? It's beyond overwhelming, so they all go back to whats safe, even if it's not the right thing for their goals or the community as a whole.

To begin to remedy this I think we have a lot of work ahead of us...starting with making the ideas and principles of Openness more accessible to those outside our community.

TL;DR: I believe that silos are a symptom of being ignorant and/or overwhelmed by the Open-anything world.

I recently used maps.me while in Europe (Germany and Poland), with no data plan and only GPS on Airplane mode. With the downloaded maps, it was great. It even included entertainment, restaurants and some transportation options.

I was actually surprised recently to find out that GPS works in airplane mode. Really fun to see what landmarks you're flying over when you see something cool out the airplane window.

For two UK charities I've worked with, the reason is that they've been tempted by the siren voices of Google.

Google offer a tempting deal to charities: free mapping, and the chance to get your content hosted on Google Maps. So, for example, Sustrans' cycle routes are now integrated into the Google's UK mapping data.

This seems to appeal particularly to the higher-ups. The developers/GIS team may be more au fait with OSM, but when the marketing director says "We have the choice of getting our routes publicised for free on Google, or... what's this obscure 'street map' site you mentioned?", it's hard to convince them. (I did try to persuade one such charity to switch to OSM-backed mapping, but the answer was "Google is a corporate partner of our charity - we can't be seen to switch away from them".)

It's a great shame especially because, as you say, the tooling available around OSM data is so much more powerful than the Google Maps API could ever be. But I'm not too worried: it'll come in time. With OSM powering more consumer-level sites by the day, it's getting easier to answer the marketing director's question.

I contribute from time to time to OSM. What bothers me a bit is my productivity when doing surveys with my phone and OSMTracker. The GPS is not precise enough to record doors locations precisely, and taking photos is time consuming (I feel quite productive when tracing roads against satellite views using JOSM, though). I can imagine that Google's stack (with their Google cars and adapted home-grown software) must be something like 100 or 1000 times more productive.

Also, OpenStreetMap provides the data, but Google aggregates the data, which makes very cheap to add/search a lot of information (ex: shops) available from on-line sources (such as web sites). I don't expect OSM to have the same amount of information any time soon.

Wi-Fi also does works in airplane mode, on Android at least...

When I was traveling overland in central Asia, everybody I met was using maps.me with OSM. The maps were of surprisingly good quality and maps.me is superb, allowing the maps for whole countries to be downloaded (ideal if you don't have a data plan) and the route calculation is quick as long as the road grid isn't too dense.

I've been looking for something like this for eternity. Thank you!

GIS Manager here. The reason silos happen in the GIS world is because of trust. Every organization has different priorities and standards when it comes to data. The accuracy you need for your building footprints might be (and probably is) unusable for someone else. Data sharing between entities is common but even then oftentimes a great deal of finesse is needed to make another organization's data work in your dataset. In the government sector there is mistrust of data requests from those who would use data for commercial interests so the default option is to charge for it or just make it unavailable.

As a regular data contributor for Openstreetmap: Openstreetmap is terribly broken in many many ways.

There's no regular checkup of the data if it's still valid. Reverting is extremely hard and there are no checks for changing the data. The multipolygon model for areas can be extremely complex and is the cause that many regions aren't touched at all anymore. In many regions it's just an import desert where already open data gets relicensed under the more restrictive OdBL license. Those areas also only rarely get touched by mappers.

One thing that I've found really helps with this is saying that OSM is "like Wikipedia for maps". These days most people understand what Wikipedia is, how it works, and trust the content. OSM really is like a cartographic Wikipedia...

What could be done to fix these issues?

I'm working on a project to create a parcel layer on top of OSM, to open source ownership data for all parcels in the US. This is relevant to my interests!
